Extended Data Fig. 2 — a, b, A porphyritic basalt clast that contains fine-grained (2 × 10 μm) apatite grains. The yellow rectangle in a is expanded in b. The apatite occurs as inclusions in Fe-rich clinopyroxene and is surrounded by tiny ilmenite aggregates. c, In a poikilitic clast, baddeleyite is rimmed by zirconolite. d, Square-shaped baddeleyite inclusions in clinopyroxene and ilmenite from an equigranular clast. Hexagonal apatite exhibits an intergranular phase between clinopyroxene and ilmenite. e, Euhedral–subhedral apatite and baddeleyite show an equilibrium texture with Fe-rich olivine (Fo < 10), clinopyroxene, and troilite. f, Baddeleyite and tranquillityite show intergrowths along the margins of clinopyroxene and Fe-rich olivine. g, In an equigranular clast, baddeleyite, tranquillityite and apatite are intergrown with Fe-rich olivine. h, Tranquillityite and apatite intergrown crystals in a poikilitic clast. Blurry pits in Zr-bearing minerals are the analytical spots from SIMS. Bdy, baddeleyite; Zrl, zirconolite; Trq, tranquillityite; Mer, merrillite; Ap, Apatite; Cpx, clinopyroxene; Ol, olivine; Pl, plagioclase; Kfs, K-feldspar; Ilm, ilmenite; Crs, cristobalite; Tro, troilite; Spl, spinel.
